Filing drawer and compartment.



HERBERT OLIN BRIGHAM, OF PROVIDENCE, RHODE ISLAND.

FILING DRAWER AND COMPARTMENT.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed January 4,1907. Serial No- 350,774.

To all whom it may concern:

Be it known that HERBERT OLIN BRIGHAM, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, has invented certain new and useful Improvements in FilingDrawers and Compartments, of which the following is a specification.

My invention relates to all kinds of filing-drawers, compartments, orreceptacles, in which documents, pamphlets, and like articles are placedfor proper keeping and ready reference.

It is my intention to provide a means whereby the said articles may bereadily removed from said drawers, receptacles, etc., after they havebeen compressed by a compressor-board, by supplying an easement at thefront of the same in the form of a combined handle which, by a singleturn thereof a movable board situated at the inside of the front ofdrawer, will be carried a short distance toward said front, therebyreducing the pressure upon the contents of drawer, allowing any or allthe contents to be readily removed, also with the same movement ofhandle, unlock the drawer at the top or sides, or bottom, as the casemay be.

It has been the custom in the past to supply all of the pressure with acompressor-board at the back of the contents of the drawer, as in theordinary vertical letter and document files. To remove any of thecontents of drawer, the compressor board is released more or less afterthe drawer has been withdrawn, and if it should be full, it would haveto be entirely withdrawn for the operation of the compressor.

The new feature shown herein permits the contents of the drawer to bereleased of sufiicient pressure for the removal thereof with ease, whenthe handle is turned, prior to the pulling out of the drawer. Iaccomplish this by placing a cam-action (plates) between the front ofthe drawer and a board upon the inside thereof, a spindle at the centerof one plate entering the center of the other plate for guidingpurposes, a cam upon the portion of handle passing through the front ofdrawer which acts upon one or more bolts used for locking purposes, anda suitable cross-bar handle at the outside front of drawer formanipulation.

I attain these objects by the special construction illustrated in theaccompanying drawings, in which Figure 1, is a sectional side view of afiling-drawer showing the contents compressed by the expansion of thecam action on cam-plate, and the locking-bolt at the top of the drawer.Fig. 2, is a sectional view of the handle to better illustrate thedetails of construction.

Similar letters refer to similar parts throughout the several views.

A is the front of drawer; B is the bottom of drawer; G is thecompressor-board; D is the board which receives the action of thecam-handle; E represents pamphlets filed; F is a cam-plate; G is the camend of handle; H is a centrally located cam acting on the locking-bolt;I is the handle in front of drawer; J is a guiding spindle in center ofcam-plate; K is the lockingbolt; L is the escutcheon plate; M socket toreceive I.

In operation, the drawer is locked and the contents are held incompressed form when the various parts are in position shown in Fig. 1:To pull out the drawer, handle I isturned which operation turns cam-endG of handle, which permits board D to move a short distance toward frontof drawer, thereby easing the pressure on the contents E, permitting thewithdrawal of any or all of the material filed. The turning of thehandle I also turns the cam H which permits lockingbolt K to fallthereby unlocking the drawer. After reference and return of contents tothe drawer, it is pushed back in its case and handle I turned whichforces back board D and compresses the contents, also forceslocking-bolt K upward causing it to enter the casing above therebylocking the drawer.

Having clearly described my invention so that those skilled in the artwill thoroughly understand the same, what I claim as my invention anddesire to secure by Letters-Patent of the United States is:

1. In a drawer or receptacle for filing books, documents or pamphlets, ameans for permitting the contents thereof to expand, consisting of a camat the inner end of the handle of the drawer, and a cam-plate upon theengaging surface of compressor board or plate C, all as and for thepurpose specified.

2. In a drawer or receptacle for filing books, documents or pamphlets,and the like, a handle for pulling out the same, having a suitable format end 1 for turning, a camend G for action upon cam-plate F, and aside-cam H for action upon locking-bolt K, in combination with the boardD carrying cam-plate F, all as shown and for purpose specified.

3. In a filing device, in combination with end thereof, a board or plateD carrying cam-plate F, a locking-bolt K in the drawer-front, and ahandle situated in line with cam-plate F and locking-bolt K, and havingcams for action thereupon.

4. As a new article of manufacture, a pressure-release and lockingdevice in combination with a handle, for filing drawers or otherreceptacle, all as shown and for purpose specified.

In testimony whereof I aflix my signature in the presence of twowitnesses.
